Patent GB-1394971-A (GB)
Title: Process for removing thermoplastic film from a mixture of thermoplastic film and wastepaper
IPC: B07B9/00
Filed: 1973-07-30
Abstract: 1394971 Separating plastics from waste paper J F LAUNDRIE 30 July 1973 [13 Sept 1972] 36213/73 Heading B2H Thermoplastics material is removed from a mixture of waste paper and thermoplastics film by heating the mixture in a stream of hot gas to cause the film to contract upon itself to form particles and mechanically separating the paper from the thermoplastics particles, e.g. by screening and/or air classification. The mixture may be comminuted prior to heating.  As shown, the mixture of waste paper and thermoplastics film is fed by means of a conveyor 11 to a dehydrator 12 supplied at 15 with a hot gas stream from a heater 14. As the mixture is transported by the gas stream, the thermoplastics film contracts upon itself to form particles and the resultant mixture of dried paper and particles is carried in the gas stream through a blower 17 to a cyclone separator 18 where gas and water vapour are separated from the mixture which is then discharged at 21 and transported by a conveyor 24 to an air classifier 23. Air drawn through ducts 25, 25' by a blower 28 carries the lighter waste paper 29 out through an exit duct 26 while the heavier thermoplastics particles 30 gravitate to the bottom of the classifier and are discharged at 27.

Title: Process for purifying methylterephthalic and 4-methyl-isophthalic  acid salts
IPC: C07C51/42
Filed: 1971-08-04
Abstract: 1343788 Separation of a mixture of methylterephthalic and 4-methylisophthalic acid salts TEIJIN Ltd 4 Aug 1971 [25 Dec 1970 (2) 28 Dec 1970] 36644/71 Heading C2C A mixture of salts of methylterephthalic acid (MTA) and 4-methylisophthalic acid (MIA), with at least one base which is (a) ammonia, (b) an aliphatic diamine of 2-12 C atoms, (c) a diamine of the formula wherein each of the symbols n is 0, 1, 2 or 3 and # is a p- or m-phenylene or p- or m-cyclohexylene group, (d) bis-(p-aminocyclohexyl)methane or (e) piperazine, is treated to increase the proportion therein of the MTA salt by contacting the salt mixture with a liquid medium comprising water and at least one hydrophilic organic solvent which is (1) as mono- or di-hydric alcohol of 1 to 3 C atoms, (2) the monomethyl or mono ethyl ether of ethylene glycol or (3) dioxane to dissolve preferentially therein the MIA salt and to leave in the solid phase the MTA salt or a mixture thereof with MIA salt containing an increased proportion of MTA salt compared with the starting salt mixture. The mixture of acids may be dissolved or suspended in the liquid medium which contains the base or to which the base may be added subsequently or alternatively, the mixture of salts may be dissolved or suspended in the water before or after adding the hydrophilic organic solvent to the water. The mixture of salts in contact with the liquid medium may be cooled and/or concentrated and the solid phase, after separation from the mother liquor, may be contacted with an acid to give MTA or a mixture thereof with MIA. The mother liquor may then be either (a) cooled and/or concentrated or (b) treated with at least one hydrophilic organic solvent as defined earlier in order to precipitate the MIA salt or a mixture thereof with MTA salt containing an increased proportion of MIA salt compared with the starting mixture. The MIA salt thus precipitated may also be converted to MIA or a mixture thereof with MTA by treatment with an acid or alternatively the mother liquor may be treated directly with the acid to produce the same result. The starting salt mixture contains preferably at least 10% by weight MTA and is preferably prepared by reacting the acids, MTA and MIA, with a stoichiometric excess of base. The contacting with the liquid medium, which preferably contains at least 10% by weight of water, may be carried out at a temperature between room temperature and slightly below the boiling point of the liquid medium. The MTA/MIA mixture of acids may be obtained by the oxidation of pseudocumene with molecular oxygen, e.g. air, at 100-250‹ C. with a catalyst comprising a compound of a heavy metal, e.g. Co or Mn, and a bromine compound. Many examples describe the separation of salts of MTA and MIA with specific bases.
Patent GB-783444-A (GB)
Title: Pattern-controlled machine tools
Inventor: CLARKE FREDERICK ROBERT MILROY
IPC: B23Q35/18
Filed: 1954-12-18
Abstract: 783,444. Copy-milling; copy-turning. PRECISION GRINDING, Ltd. Feb. 23, 1956 [Dec. 18, 1954], No. 36674/54. Class 83 (3). A tracer-head for an hydraulically-operated lathe or milling-machine comprises a tracerspindle 7 having axial and lateral freedom of movement, a valve-member 3 which carries and is movable by the spindle and has only lateral freedom of movement, and a valve member 21 having axial freedom of movement mounted coaxially with and movable by axial or lateral movements of the spindle. The milling-machine has adjustable work and pattern-tables 38, 39 and a milling cutter 40 and a tracer 5 mounted on a slide 42 movable vertically on a slide 43 by a piston 46 controlled by the valve 21. The slide 43 is movable by a piston 50 in a cylinder 48 on a slide 49 movable similarly by a piston- and-cylinder 52, 53 under the control of the valve 3. The tracer spindle 7 carrying the tracer 5 slides on balls 11 in a sleeve 4 secured to the valve 3. The weight of the tracer spindle is partly taken by a spring 10. The valve 3 controls the flow of high-pressure liquid to four narrow ports 19 leading to two pairs of diametrically-opposite passages 14 connected to lines 57, Fig. 8, in the respective controlling means for the slides 43, 49. The valve 21, for the slide 42, is biased by a spring 33 and is actuated by the tracer 5 through a ball 36 and a thrust-piece 29 moving on balls 32. A land 28 on the valve 21 controls the flow of liquid to passages 23, 25 but allows a restricted flow at all times. In operation, low-pressure liquid is supplied both to the piston 53 to traverse the slide 49 slowly and also to one or other end of the cylinder 48, Fig. 8, through one of the pipes 64, to reciprocate the slide 43. At the end of each traverse of the slide 43, a valve is manually or mechanically operated to reverse the slide movement by supplying liquid to the other pipe 64. If, however, the valve 3 is actuated by the tracer, high-pressure liquid is supplied from a passage 14 to one of the lines 57, causing a valve 55 to move against a spring 56 and restrict the flow of low-pressure liquid from the cylinder 48; further movement of the valve 55 causes highpressure liquid to enter one end of the cylinder and override the low pressure at the opposite end. Thus, when a slope is encountered on the pattern, the valve 21 raises the cutter. If the slope is abrupt, the tracer is moved rearwardly and causes stopping or reversing of the traverse. The flow of high-pressure liquid to exhaust is controlled by adjustable valves 60 and the rest position of the valves 55 is determined by screws 61.

A nut runner or like torquing device comprising a manifold for receiving high and lower power transmission lines, a tool connected to the manifold and rotatable between first and second operating positions, and means for biasing the tool to the first position during low power supply, the tool rotating against the biasing means to the second position when the torque is increased and high power is supplied. The machine comprises a pair of tools 20, 20A, Fig. 1, each of which is driven by an hydraulic motor 21, means 10 for carrying the angular position of the tools according to the resistance to rotation, and means 30 which co-operates with means 10 to vary the fluid flow to the motors, and thus vary the torque applied to the work. Each tool carries a chuck 23 and a pin 25, Fig. 3, which is urged into engagement with a pin 12 during the low torque, high speed, period of operation, the tension in the spring being overcome, thus allowing pin 25 to engage a second pin 13 when the torque reaches a predetermined level. Means 30, Figs. 5, 6, comprises a bush 31 for each tool, having angularly and axially spaced high and low pressure ports 32, 33 respectively, which cooperate with similar ports 17, 18, in a stud 15 carried by the tool. High pressure fluid is supplied at 41, Figs. 1, 2, passes through a throttling valve 42 actuated by trigger 43, and thence via a high pressure passage 35 to ports 32, and also via a pressure regulator 45, and a low pressure passage to ports 33. In operation, with the pin 25 engaging the pin 12 and the low pressure port 33 aligned with the port 18, each tool is driven at low torque. When the resistance reaches a predetermined value, the motor 21 stalls, the tool 20 rotates against the spring 26 until the pin 25 engages the pin 13, and the high pressure ports 17, 32 are aligned to supply high-pressure fluid to the motor and provide a high torque. In a modification, Fig. 7, a tool 53 is driven by an electric motor 52, connected by a transformer 50 and a switch 51 to a source of electricity 54. When the switch 51 is closed, low power is supplied, and when the motor stalls, the tool 53 rotates, and through mechanical or servo means 55 resets transformer 50 to supply high power. In a further modification, Fig. 8, the supply of high and low pressure fluid from lines 35, 36 is controlled by a solenoid valve 56, actuated by means 59 connected to the tool. Lamps 60-62, Fig. 9, connected to the power source 54 by switches 63-65, may be supplied to indicate the particular condition of the tool, i.e., high torque, low torque and maximum torque.
